The tapping drive mechanism causes the treatment elements 9 and 10 to perform a tapping operation by swinging the treatment elements 9 and 10 in the front-rear direction. The kneading drive mechanism causes the treatment elements 9 and 10 to perform a kneading operation by eccentrically rotating the treatment elements 9 and 10.

たたき駆動機構は、たたき用モータ１１と、ギア１２と、たたき用シャフト１３と、左用偏心回動体と、右用偏心回動体と、左側突出部と、右側突出部と、を含む。たたき用シャフト１３には、左用偏心回動体と及び右用偏心回動体が固定されている。前方に向かって延びる左側突出部の後端には、たたき用シャフト１３と同心の貫通孔が設けられている。たたき用シャフト１３が回転すると、左用偏心回動体が左側突出部の貫通孔を摺動しながら回転する。前方に向かって延びる右側突出部の後端には、たたき用シャフト１３と同心の貫通孔が設けられている。たたき用シャフト１３が回転すると、右用偏心回動体が右側突出部の貫通孔を摺動しながら回転する。たたき用シャフト１３に取り付けられた左側突出部の前端は左側ボールジョイントによってアームＡＭ１に連結されている。たたき用シャフト１３に取り付けられた右側突出部の前端は右側ボールジョイントによってアームＡＭ２に連結されている。たたき用モータ１１が駆動すると、ギア１２を介してたたき用シャフト１３に駆動力が印加され、たたき用シャフト１３が回転する。たたき用シャフト１３の回転に伴って、後述する揉み用シャフト１５を枢軸としてアームＡＭ１及びＡＭ２が揺動する。   The tapping drive mechanism includes a tapping motor 11, a gear 12, a tapping shaft 13, a left eccentric rotary member, a right eccentric rotary member, a left protrusion, and a right protrusion. A left eccentric rotating body and a right eccentric rotating body are fixed to the beating shaft 13. At the rear end of the left protruding portion extending forward, a through hole is provided concentrically with the beating shaft 13. When the beating shaft 13 rotates, the left eccentric rotating body rotates while sliding through the through hole of the left protruding portion. At the rear end of the right protrusion protruding forward, a through hole is provided concentrically with the beating shaft 13. When the beating shaft 13 rotates, the right eccentric rotating body rotates while sliding through the through hole of the right protruding portion. The front end of the left protrusion attached to the beating shaft 13 is connected to the arm AM1 by a left ball joint. The front end of the right protruding portion attached to the beating shaft 13 is connected to the arm AM2 by a right ball joint. When the tapping motor 11 is driven, a driving force is applied to the tapping shaft 13 via the gear 12, and the tapping shaft 13 rotates. With the rotation of the tapping shaft 13, the arms AM <b> 1 and AM <b> 2 swing about the kneading shaft 15 as a pivot.

アームＡＭ１は施療子９を支持し、アームＡＭ２は施療子１０を支持する。施療子９はアームＡＭ１の前端に取り付けられており、施療子１０はアームＡＭ２の前端に取り付けられている。アームＡＭ１の前端とアームＡＭ２の前端との左右方向幅Ｗ１は、アームＡＭ１の後端部とアームＡＭ１の後端との左右方向幅Ｗ２より狭い。アームＡＭ１の後端部とアームＡＭ１の後端との間には第３平板部材Ｐ３が配置され幅Ｗ２が広くなるため、幅Ｗ１を幅Ｗ２より狭くすることで施療子９及び１０を適切な位置に配置することができる。なお、第３平板部材Ｐ３の左右方向長さを短くする等の対策によって幅Ｗ２がさほど広くならないのであれば、本実施例とは異なり幅Ｗ１を幅Ｗ２以上にしてもよい。   The arm AM1 supports the treatment element 9, and the arm AM2 supports the treatment element 10. The treatment element 9 is attached to the front end of the arm AM1, and the treatment element 10 is attached to the front end of the arm AM2. The lateral width W1 between the front end of the arm AM1 and the front end of the arm AM2 is smaller than the lateral width W2 between the rear end of the arm AM1 and the rear end of the arm AM1. Since the third flat plate member P3 is disposed between the rear end of the arm AM1 and the rear end of the arm AM1, and the width W2 is increased, the widths W1 are made smaller than the width W2 so that the treatment elements 9 and 10 can be appropriately positioned. Position. If the width W2 does not increase so much due to measures such as shortening the length of the third flat plate member P3 in the left-right direction, the width W1 may be made larger than the width W2 unlike the present embodiment.

揉み駆動機構は、揉み用モータ１４と、揉み用シャフト１５と、偏心回動体と、を含む。左右方向に延びている揉み用シャフト１５に、左右一対の偏心回動体が固定されている。揉み用シャフト１５は、左側の偏心回動体を介してアームＡＭ１の後部を支持し、右側の偏心回動体を介してアームＡＭ２の後部を支持する。揉み用シャフト１５に揉み用モータ１４が連動連結される。揉み用モータ１４が駆動すると、揉み用シャフト１５が回転し、揉み用シャフト１５に固定されている左右一対の偏心回動体も回転する。左右一対の偏心回動体の回転によってアームＡＭ１及びＡＭ２は上下、左右、前後にそれぞれ揺動する。   The kneading drive mechanism includes a kneading motor 14, a kneading shaft 15, and an eccentric rotating body. A pair of left and right eccentric rotating bodies is fixed to the kneading shaft 15 extending in the left-right direction. The kneading shaft 15 supports the rear part of the arm AM1 via the left eccentric rotary body, and supports the rear part of the arm AM2 via the right eccentric rotary body. The kneading motor 14 is linked to the kneading shaft 15. When the kneading motor 14 is driven, the kneading shaft 15 rotates, and the pair of left and right eccentric rotating bodies fixed to the kneading shaft 15 also rotate. The arms AM1 and AM2 swing up and down, left and right, and back and forth by the rotation of the pair of left and right eccentric rotating bodies.

揉み用シャフト１５の左端部を回転可能に支持する軸受け部が第１平板部材Ｐ１の内部に配置される。また、たたき用シャフト１３の左端部を回転可能に支持する軸受け部も第１平板部材Ｐ１の内部に配置される。   A bearing that rotatably supports the left end of the kneading shaft 15 is disposed inside the first flat plate member P1. In addition, a bearing for rotatably supporting the left end of the beating shaft 13 is also disposed inside the first flat plate member P1.

揉み用シャフト１５の右端部を回転可能に支持する軸受け部が第２平板部材Ｐ２の内部に配置される。また、たたき用シャフト１３の右端部を回転可能に支持する軸受け部も第２平板部材Ｐ２の内部に配置される。   A bearing for rotatably supporting the right end of the kneading shaft 15 is disposed inside the second flat plate member P2. Further, a bearing for rotatably supporting the right end of the beating shaft 13 is also disposed inside the second flat plate member P2.

揉み用シャフト１５の中間部を回転可能に支持する軸受け部が第３平板部材Ｐ３の内部に配置される。また、たたき用シャフト１３の中間部を回転可能に支持する軸受け部も第３平板部材Ｐ３の内部に配置される。   A bearing portion rotatably supporting an intermediate portion of the kneading shaft 15 is disposed inside the third flat plate member P3. A bearing portion rotatably supporting an intermediate portion of the beating shaft 13 is also disposed inside the third flat plate member P3.

揉み用シャフト１５の左端部、右端部、及び中間部、すなわち揉み用シャフト１５の３箇所で揉み駆動機構を支持する構成であるため、第１平板部材Ｐ１及び第２平板部材Ｐ２に高い剛性が要求されない。したがって、揉み駆動機構を収納して支持する大型のケースが不要となり、その結果、マッサージユニット１の小型化を図ることができる。   Since the left end portion, the right end portion, and the middle portion of the kneading shaft 15 are configured to support the kneading drive mechanism at the three positions of the kneading shaft 15, the first flat plate member P1 and the second flat plate member P2 have high rigidity. Not required. Therefore, a large case for accommodating and supporting the massaging drive mechanism becomes unnecessary, and as a result, the size of the massage unit 1 can be reduced.

図６に示すように、第３平板部材Ｐ３の左側面には第３平板部材Ｐ３の内外を連通する連通孔Ｈ１及びＨ２が設けられる。第３平板部材Ｐ３の右側面には連通孔Ｈ１及びＨ２を左右方向にそって移動させた位置に連通孔が設けられる。第３平板部材Ｐ３は、上方に突出する突出部Ｐ３Ａを後部且つ上部に備える。突出部Ｐ３Ａには、連通孔Ｈ２及び連通孔Ｈ２に対応する右側面の連通孔が設けられる。   As shown in FIG. 6, communication holes H1 and H2 are provided on the left side surface of the third flat plate member P3 to communicate the inside and outside of the third flat plate member P3. On the right side surface of the third flat plate member P3, a communication hole is provided at a position where the communication holes H1 and H2 are moved along the left-right direction. The third flat plate member P3 includes a protruding portion P3A protruding upward at a rear portion and an upper portion. The protruding portion P3A is provided with a communication hole H2 and a communication hole on the right side corresponding to the communication hole H2.

揉み用シャフト１５が連通孔Ｈ１及び連通孔Ｈ１に対応する右側面の連通孔を通じて第３平板部材Ｐ３を貫通する。たたき用シャフト１３が連通孔Ｈ２及び連通孔Ｈ２に対応する右側面の連通孔を通じて第３平板部材Ｐ３を貫通する。第３平板部材Ｐ３の左側面には連通孔Ｈ１より後方且つ連通孔Ｈ２より下方に第３の連通孔が設けられる。第３の連通孔に揉み用モータ１４の回転シャフトが挿入される。連通孔Ｈ２は連通孔Ｈ１及び第３の連通孔より上方に配置されるため、連通孔Ｈ２を突出部Ｐ３Ａに設けることで第３平板部材Ｐ３の体積を小さくすることができる。   The kneading shaft 15 passes through the third flat plate member P3 through the communication hole H1 and the communication hole on the right side corresponding to the communication hole H1. The beating shaft 13 penetrates the third flat plate member P3 through the communication hole H2 and the communication hole on the right side corresponding to the communication hole H2. A third communication hole is provided on the left side surface of the third flat plate member P3 behind the communication hole H1 and below the communication hole H2. The rotary shaft of the kneading motor 14 is inserted into the third communication hole. Since the communication hole H2 is disposed above the communication hole H1 and the third communication hole, the volume of the third flat plate member P3 can be reduced by providing the communication hole H2 in the protruding portion P3A.

第３平板部材Ｐ３は、前後方向及び上下方向に延びる板状部材であり、左右方向長さが前後方向の長さより短く且つ上下方向の長さより短い。第３平板部材Ｐ３の前端には第４平板部材Ｐ４の本体部が第３平板部材Ｐ３に対して略垂直に固定されている。   The third flat plate member P3 is a plate-like member extending in the front-rear direction and the up-down direction, and has a length in the left-right direction shorter than the length in the front-rear direction and shorter than the length in the up-down direction. At the front end of the third flat plate member P3, the main body of the fourth flat plate member P4 is fixed substantially perpendicular to the third flat plate member P3.

図７に示すように、第４平板部材Ｐ４は、第４平板部材Ｐ４の本体部以外に、第４平板部材Ｐ４の本体部の左辺から後方に延びる第１折り返し部Ｐ４Ａと、第４平板部材Ｐ４の本体部の右辺から後方に延びる第２折り返し部Ｐ４Ｂと、を備える。   As shown in FIG. 7, the fourth flat plate member P4 includes, in addition to the main body portion of the fourth flat plate member P4, a first folded portion P4A extending rearward from the left side of the main body portion of the fourth flat plate member P4, and a fourth flat plate member. A second folded portion P4B extending rearward from the right side of the main body of P4.

第１折り返し部Ｐ４Ａの下部が回転軸ＡＸ１回りに回動可能にベース部材部品２Ｄに取り付けられ、第２折り返し部Ｐ４Ｂの下部が回転軸ＡＸ１回りに回動可能にベース部材部品２Ｅに取り付けられる（図２参照）。なお、回転軸ＡＸ１は左右方向に沿って延びる軸である。したがって、第３平板部材Ｐ３は、第４平板部材Ｐ４を介して、回転軸ＡＸ１回りに回動可能にベース部材に取り付けられる。   The lower part of the first folded part P4A is attached to the base member part 2D so as to be rotatable around the rotation axis AX1, and the lower part of the second folded part P4B is attached to the base member part 2E so as to be rotatable about the rotation axis AX1 ( (See FIG. 2). Note that the rotation axis AX1 is an axis extending along the left-right direction. Therefore, the third flat plate member P3 is attached to the base member via the fourth flat plate member P4 so as to be rotatable around the rotation axis AX1.

図７に示すように、第４平板部材Ｐ４の左右方向長さＬ２は第３平板部材Ｐ３の前端の左右方向長さＬ１より長い。これにより、揉み駆動機構又はたたき駆動機構が動作中に振動によって第３平板部材Ｐ３の位置がぐらつくことを抑制することができる。   As shown in FIG. 7, the left-right length L2 of the fourth flat plate member P4 is longer than the left-right length L1 of the front end of the third flat plate member P3. Accordingly, it is possible to prevent the position of the third flat plate member P3 from wobbling due to vibration during the operation of the massaging drive mechanism or the knocking drive mechanism.

マッサージユニット１は、連結ロッド１６及び１７をさらに備える。連結ロッド１６及び１７は、左右方向に沿って延びる棒状部材であって、第１平板部材Ｐ１と第２平板部材Ｐ２を連結する。言い換えると、マッサージユニット１は、揉み駆動機構及びたたき駆動機構を収納するケースを備えていない。したがって、第１平板部材Ｐ１及び第２平板部材Ｐ２は、揉み駆動機構及びたたき駆動機構を収納するケースの一部を構成しない。   Massage unit 1 further includes connecting rods 16 and 17. The connecting rods 16 and 17 are rod-shaped members extending in the left-right direction, and connect the first flat plate member P1 and the second flat plate member P2. In other words, the massage unit 1 does not include a case for accommodating the kneading drive mechanism and the tapping drive mechanism. Therefore, the first flat plate member P1 and the second flat plate member P2 do not constitute a part of a case for accommodating the kneading drive mechanism and the tapping drive mechanism.

連結ロッド１６は、たたき用シャフト１３より前方且つ揉み用シャフト１５より後方に配置される。また、図２〜図５に示す状態において、連結ロッド１６は、たたき用シャフト１３及び揉み用シャフト１５より上方に配置される。連結ロッド１７は、たたき用シャフト１３より後方に配置される。また、図２〜図５に示す状態において、連結ロッド１７は、揉み用シャフト１５より下方に配置される。   The connecting rod 16 is disposed forward of the striking shaft 13 and rearward of the kneading shaft 15. In addition, in the state shown in FIGS. 2 to 5, the connecting rod 16 is disposed above the striking shaft 13 and the kneading shaft 15. The connecting rod 17 is arranged behind the beating shaft 13. In addition, in the state shown in FIGS. 2 to 5, the connecting rod 17 is disposed below the kneading shaft 15.

第１折り返し部Ｐ４Ａ及び第２折り返し部Ｐ４Ｂの各上部が連結ロッド１６に回動不可能に取り付けられる（図２参照）。これにより、揉み駆動機構又はたたき駆動機構が動作中に振動によって第３平板部材Ｐ３の位置がぐらつくことを抑制することができる。   The upper portions of the first folded portion P4A and the second folded portion P4B are non-rotatably attached to the connecting rod 16 (see FIG. 2). Accordingly, it is possible to prevent the position of the third flat plate member P3 from wobbling due to vibration during the operation of the massaging drive mechanism or the knocking drive mechanism.

マッサージユニット１は、進退軸１８と、ピニオンギア１９及び２０と、進退用モータ２１と、をさらに備える。進退軸１８は左右方向に沿って延びる。進退軸１８の左側にはピニオンギア１９が固定され、進退軸１８の右側にはピニオンギア２０が固定される。進退軸１８に進退用モータ２１が連動連結される。回転伝達部Ｒ２によって進退軸１８に進退用モータ２１が連動連結される。回転伝達部Ｒ２は、軸受部及び回転軸方向を変更するためのギア機構を含む。   The massage unit 1 further includes an advance / retreat shaft 18, pinion gears 19 and 20, and an advance / retreat motor 21. The reciprocating shaft 18 extends along the left-right direction. A pinion gear 19 is fixed to the left side of the reciprocating shaft 18, and a pinion gear 20 is fixed to the right side of the reciprocating shaft 18. The forward / backward motor 21 is linked to the forward / backward shaft 18. The forward / backward motor 21 is linked to the forward / backward shaft 18 by the rotation transmitting unit R2. The rotation transmission unit R2 includes a bearing unit and a gear mechanism for changing the direction of the rotation axis.

第１平板部材Ｐ１及び第２平板部材Ｐ２の各上部に円弧状のラックが設けられている。ピニオンギア１９は第１平板部材Ｐ１に設けられるラックに噛み合っており、ピニオンギア２０は第２平板部材Ｐ２に設けられるラックに対して噛み合っている。進退軸１８の回転に伴って、ピニオンギア１９及び２０が回転しながら、ラックに対して移動する。ピニオンギア１９及び２０のラックに対する移動により、第１平板部材Ｐ１及び第２平板部材Ｐ２が回転軸ＡＸ１を中心に前後方向に回動し、施療子９及び１０が前後方向に進退移動する。すなわち、第１平板部材Ｐ１及び第２平板部材Ｐ２が回転軸ＡＸ１を中心に前後方向に回動することで、施療子９及び１０の突出量が大幅に変更する。例えば、図２〜図５に示す状態から第１平板部材Ｐ１及び第２平板部材Ｐ２を前方向に回動させることで図８〜図９に示す状態に変化させることができる。   An arc-shaped rack is provided above each of the first flat plate member P1 and the second flat plate member P2. The pinion gear 19 meshes with a rack provided on the first flat plate member P1, and the pinion gear 20 meshes with a rack provided on the second flat plate member P2. With the rotation of the reciprocating shaft 18, the pinion gears 19 and 20 rotate and move with respect to the rack. The movement of the pinion gears 19 and 20 with respect to the rack causes the first flat plate member P1 and the second flat plate member P2 to rotate in the front-rear direction around the rotation axis AX1, and the treatment elements 9 and 10 move forward and backward. That is, when the first flat plate member P1 and the second flat plate member P2 rotate in the front-rear direction about the rotation axis AX1, the protrusion amounts of the treatment elements 9 and 10 are significantly changed. For example, the state shown in FIGS. 2 to 5 can be changed to the state shown in FIGS. 8 to 9 by rotating the first flat plate member P1 and the second flat plate member P2 forward.

＜３．その他＞
上記実施形態は、全ての点で例示であって、制限的なものではないと考えられるべきであり、本発明の技術的範囲は、上記実施形態の説明ではなく、特許請求の範囲によって示されるものであり、特許請求の範囲と均等の意味及び範囲内に属する全ての変更が含まれると理解されるべきである。 <3. Others>
The above embodiments are to be considered in all respects as illustrative and not restrictive, and the technical scope of the present invention is indicated not by the description of the embodiments but by the claims. It is to be understood that the present invention includes all modifications that fall within the meaning and scope equivalent to the claims.

例えば上記実施形態においては、いわゆる椅子式マッサージ機を例に挙げて説明したが、本発明に係るマッサージユニットはいわゆるベッド式マッサージ機などにも搭載可能である。   For example, in the above embodiment, a so-called chair-type massage machine has been described as an example, but the massage unit according to the present invention can be mounted on a so-called bed-type massage machine.

また、例えば上記実施形態においては、第３平板部材Ｐ３が、第４平板部材Ｐ４を介して回転軸ＡＸ１回りに回動可能にベース部材に取り付けられているが、図１０〜図１２に示すように、第３平板部材Ｐ３を、左右方向に延びる所定の回転軸回りに回動可能にベース部材に直接取り付けてもよい。なお、図１０〜図１２において、図２、図６、及び図７と同一の部分には同一の符号を付している。図１１に示すように、第３平板部材Ｐ３の前部且つ下部に、前方および下方に突出する突出部Ｐ３Ｂを設け、突出部Ｐ３Ｂをベース部材への取り付け箇所にすることで、第３平板部材Ｐ３の体積を小さくすることができる。   Further, for example, in the above-described embodiment, the third flat plate member P3 is attached to the base member so as to be rotatable around the rotation axis AX1 via the fourth flat plate member P4, but as shown in FIGS. Alternatively, the third plate member P3 may be directly attached to the base member so as to be rotatable around a predetermined rotation axis extending in the left-right direction. 10 to 12, the same parts as those in FIGS. 2, 6, and 7 are denoted by the same reference numerals. As shown in FIG. 11, a protrusion P3B that protrudes forward and downward is provided at a front portion and a lower portion of the third plate member P3, and the protrusion P3B is used as an attachment portion to the base member, thereby making the third plate member P3. The volume of P3 can be reduced.

また、例えば上記実施形態においては、たたき用モータ１１が左右方向において第３平板部材Ｐ３を跨いで第３平板部材Ｐ３の左右両側に配置され、揉み用モータ１４が第３平板部材Ｐ３の左側に配置されているが、図１３に示す変形例のように、第３平板部材Ｐ３の右側にたたき用モータ１１を配置し、第３平板部材Ｐ３の左側に揉み用モータ１４を配置してもよく、図１３に示す変形例とは逆に、第３平板部材Ｐ３の右側に揉み用モータ１４を配置し、第３平板部材Ｐ３の左側にたたき用モータ１１を配置してもよい。たたき用モータ１１及び揉み用モータ１４の一方を第３平板部材Ｐ３の右側に配置し、たたき用モータ１１及び揉み用モータ１４の他方を第３平板部材Ｐ３の左側に配置することで、マッサージユニット１の重量バランスが良好になる。   Further, for example, in the above embodiment, the tapping motor 11 is disposed on the left and right sides of the third flat plate member P3 across the third flat plate member P3 in the left-right direction, and the kneading motor 14 is provided on the left side of the third flat plate member P3. Although it is arranged, the tapping motor 11 may be arranged on the right side of the third flat plate member P3 and the kneading motor 14 may be arranged on the left side of the third flat plate member P3, as in the modification shown in FIG. 13, the kneading motor 14 may be arranged on the right side of the third flat plate member P3, and the tapping motor 11 may be arranged on the left side of the third flat plate member P3. By placing one of the tapping motor 11 and the kneading motor 14 on the right side of the third flat plate member P3 and arranging the other of the tapping motor 11 and the kneading motor 14 on the left side of the third flat plate member P3, a massage unit is provided. 1 has a good weight balance.

また、例えば上記実施形態においては、たたき用モータ１１及び揉み用モータ１４の集合体の重心が第３平板部材Ｐ３の左側に位置し、進退用モータの重心も第３平板部材Ｐ３の左側に位置しているが、たたき用モータ１１及び揉み用モータ１４の集合体の重心と進退用モータの重心との一方が第３平板部材Ｐ３の左側に位置し、たたき用モータ１１及び揉み用モータ１４の集合体の重心と進退用モータの重心との他方が第３平板部材Ｐ３の右側に位置するように各モータを配置してマッサージユニット１の重量バランスを良好にしてもよい。   Further, for example, in the above-described embodiment, the center of gravity of the assembly of the tapping motor 11 and the kneading motor 14 is located on the left side of the third plate member P3, and the center of gravity of the advance / retreat motor is also located on the left side of the third plate member P3. However, one of the center of gravity of the assembling of the tapping motor 11 and the kneading motor 14 and the center of gravity of the advancing / retracting motor 14 are located on the left side of the third flat plate member P3. Each motor may be arranged so that the other of the center of gravity of the assembly and the center of gravity of the forward / backward motor is located on the right side of the third flat plate member P3 to improve the weight balance of the massage unit 1.

また、例えば上記実施形態と異なり、揉み用シャフト１５の右側と左側とで逆方向にねじをきり、アームＡＭ１の後端及びアームＡＭ２の後端が揉み用シャフト１５の回転によって揉み用シャフト１５に沿って直動するようにしてもよい。このような変形例によると、揉み用シャフト１５が一方向に回転することで施療子９と施療子１０との間隔が拡がり、揉み用シャフト１５が当該一方向とは逆方向に回転することで施療子９と施療子１０との間隔が狭まる。すなわち、アームＡＭ１及びＡＭ２を左右に揺動させることができる。そして、たたき用モータ１１及び進退用モータ２１を駆動させることで、アームＡＭ１及びＡＭ２を上下、左右に揺動させることができるので、偏心回動体を用いずに揉み駆動機構を実現できることができる。すなわち、揉み駆動機構を簡易な構造にすることができる。   Further, for example, unlike the above-described embodiment, the right and left sides of the kneading shaft 15 are threaded in opposite directions, and the rear end of the arm AM1 and the rear end of the arm AM2 are formed on the kneading shaft 15 by the rotation of the kneading shaft 15. It may be made to move directly along. According to such a modification, the distance between the treatment element 9 and the treatment element 10 is increased by rotating the kneading shaft 15 in one direction, and the kneading shaft 15 is rotated in the opposite direction to the one direction. The distance between the treatment element 9 and the treatment element 10 is reduced. That is, the arms AM1 and AM2 can swing right and left. By driving the tapping motor 11 and the advance / retreat motor 21, the arms AM1 and AM2 can be swung up and down, left and right, so that a kneading drive mechanism can be realized without using an eccentric rotating body. That is, the massaging drive mechanism can have a simple structure.
